Exhibit 10.30

                              EMPLOYMENT AGREEMENT


                  This EMPLOYMENT AGREEMENT (the "Agreement"), dated
as of May 15, 1997, is by and between Magellan International,
Inc. (the "Company") and Frederick A. Landman (the
"Executive").

                  In consideration of the promises in this Agreement, the
mutuality and sufficiency of which are hereby acknowledged, the parties agree as
follows:

                  1. Employment. The Company hereby employs the
Executive and the Executive hereby accepts employment by the
Company under the terms and conditions set forth in this
Agreement.

                  2. Term. The term of the Executive's employment under this
Agreement (the "Employment Term") will commence at the Effective Time of the
Merger, as such terms are defined in the Agreement and Plan of Merger (the
"Agreement and Plan of Merger") dated September 20, 1996 between Hughes
Communications Inc., certain of its affiliates, and PanAmSat Corporation, and
will end three years later; unless the Executive's employment is terminated
under Paragraph 7, in which event the Agreement will terminate on the date of
termination pursuant to Paragraph 7. After the expiration of the Employment
Term, it is anticipated that no employment agreement will be required to define
the employment status of

the Executive. However, if the term of this Agreement is extended by the Company
and the Executive, in writing, the period of time during which the Executive is
actively employed by the Company pursuant to this Agreement shall be referred to
herein as the "Employment Period."

                  3. Title and Duties. The Executive will serve as the President
and Chief Executive Officer of the Company and be based at the Company's
headquarters in Greenwich, Connecticut. The Executive shall be responsible for,
among other things, the profitability and total performance of the Company,
maintenance of all legal and statutory requirements applicable to the Company,
and, in accordance with the by-laws of the Company, the management of all
personnel of the Company, selection of management staff, outside consultants and
counsel, and such other duties and responsibilities that may be assigned to him
from time to time by the Board of Directors of the Company that are consistent
with his position. The Executive agrees to devote his full business attention,
skill and energy to the duties set forth herein and to the business of the
Company, to use his efforts to promote the success of the Company's business,
and to cooperate with the Board of Directors in the advancement of the best
interests of the Company. The Executive will serve, without additional
compensation, as a director of the Company. Nothing in this Agreement prevents
Executive from engaging in


                                       2

<PAGE>


additional activities in connection with personal investments and community
affairs that are not inconsistent with the Executive's duties hereunder.

                  4. Compensation and Benefits. During the Employment Period,
Executive shall receive the following compensation and benefits:

                      (a) Base Salary. In consideration for Executive's services
to the Company during the Employment Term, Executive shall receive a base salary
at the annual rate of Six Hundred Thousand Dollars (U.S. $600,000) ("Base
Salary"). The Base Salary shall be payable in accordance with the Company's
customary payroll practices for other executive employees, from which the
Company shall withhold and deduct all federal and state income, social security
and disability taxes and other deductions as required by applicable laws. During
the Employment Period, the Base Salary will be reviewed by the Board of
Directors on an annual basis and may be adjusted upward to reflect the
Executive's performance and the scope and success of the Company.

                      (b) Incentive Bonuses. The Executive shall be eligible to
receive incentive bonuses (the "Incentive Bonus") on an annual basis, based on
meeting financial performance criteria ("Financial and Business Goals") for the
Company with respect to revenue growth, cash flow and other financial criteria
agreed upon in advance each year by the Executive and

                                       3

<PAGE>


the Company. The Incentive Bonus shall be based on a target dollar amount. The
target dollar amount for calendar year 1997 shall be $400,000 and shall not be
prorated. The Executive shall receive an Incentive Bonus equal to the target
dollar amount if the Financial and Business Goals are met. To the extent the
Company exceeds the Financial and Business Goals by up to 25%, the Board of
Directors will increase the target dollar amount by up to 50%, or, if the
Company fails to meet the Financial and Business Goals by no more than 20%, the
Board of Directors may reduce the target dollar amount to a number no lower than
80% of such target dollar amount. If more than two of the Financial and Business
Goals are missed by more than 20%, the Company shall not be required to pay any
award. If an award is earned, the Executive shall receive an Incentive Bonus
equal to the adjusted target dollar amount.

                      (c) Employee Benefits. The Executive shall be entitled to
participate in the Company's employee benefit plans and policies in effect from
time to time, including but not limited to medical benefits, life insurance and
other fringe benefits, as may be in effect from time to time, under the same
terms and conditions as similarly situated executive employees.

                      (d) Vacation and Holidays. The Executive shall be entitled
to paid vacation time and paid holidays to the same extent as similarly situated
executive employees of


                                       4

<PAGE>


the Company may be entitled in accordance with the policies of the Company in
effect from time to time.

                           (e) Housing Allowance. The Company agrees that, if
Executive's duties require him to spend 30% of his working time in California,
the Company will pay for the costs of renting suitable housing for the Executive
and his family and will provide a reasonable allowance for related expenses.

                  5. Stock Options.

                   (a) In addition to the Base Salary and other benefits
provided above, the Company shall promptly grant stock options (the "Options")
to the Executive to purchase 93,750 shares of common stock of the Company at an
exercise price equal to fair market value of the stock of the Company on the
date of the grant pursuant to the Company's Long term Stock Incentive Plan (the
"Stock Option Plan").

                   (b) The Options shall vest as follows:

                       o   1/3 of the Options shall vest on the first
                           anniversary of the date of the Merger, if the
                           Executive is employed by the Company on such date;

                       o   1/3 of the Options shall vest on the second
                           anniversary of the date of the Merger, if the
                           Executive is employed by the Company on such date;
                           and



                                       5

<PAGE>



                       o   1/3 of the Options shall vest on the third
                           anniversary of the date of the Merger, if the
                           Executive is employed by the Company on such date.

                   (c) The Company agrees that any shares purchased by the
Executive will be registered for resale on a Registration Statement filed on
Form S-8 or S-3, which Registration Statement will be duly filed with the
Securities and Exchange Commission.

                   (d) The Executive also shall be eligible for additional stock
options as may be granted to executive employees of the Company from time to
time.

                   (e) Except as otherwise provided in this Agreement, the
provisions of the Stock Option Plan shall govern in respect of the Executive's
rights and obligations relating to the Options.

                  6. Reimbursement of Expenses.

                     During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable and necessary
expenses incurred by him in performing services hereunder, provided that the
Executive properly accounts for such expenses in accordance with the Company's
policy then in effect.

                  7.  Termination of Employment.


                                       6

<PAGE>





                      (a) Death. The Executive's employment shall terminate
immediately upon his death.
                           
                      (b) Disability. The Employment Period shall be deemed to
have expired upon the occurrence of a "Disability." For purposes of this
Agreement, "Disability" means a determination by the Company in accordance with
applicable law that, as a result of a physical or mental illness, the Executive
is unable to perform the essential functions of his job performance with or
without reasonable accommodation. The Company, by action of the Board of
Directors of the Company after giving the Executive and his medical and legal
advisors an opportunity to meet with the Board of Directors, may only render
such determination of disability if (i) the Executive is chemically dependent
and refuses or is unsuccessful in chemical dependency treatment or (ii) the
Executive has been unable to substantially perform his duties for one hundred
and twenty (120) consecutive days or for one hundred and fifty (150) days during
any twelve (12) month period because of physical or mental infirmity.
                           
                      (c) Termination for Material Breach. Upon delivery of
written notice of termination for "Material Breach" (as defined below) from the
Company to the Executive, the Employment Period shall be deemed to have expired.
Termination for "Material Breach" shall mean termination based on (i) the
Executive's material breach of this Agreement, (ii) the Executive's wilful
contravention of specific written


                                       7

<PAGE>





lawful directions from the Board of Directors acting by majority action (and not
through a committee thereof) or (iii) conduct by the Executive in connection
with his employment that is fraudulent, felonious or grossly negligent.
Termination for "Material Breach" shall be by action of the Board of Directors
of the Company after giving the Executive and his legal advisors an opportunity
to meet with the Board of Directors, and, with respect to any termination based
upon clauses (i) or (ii) of the preceding sentence, after giving the Executive
30 days to cure any Material Breach if such Material Breach can be cured. In the
event of any Material Breach of this Agreement, the Executive shall be liable to
the Company for such damages as the law may allow.
                           
                      (d) Resignation. The Executive may voluntarily resign his
employment hereunder (i) at any time during the first year following the
Effective Date, for any reason or no reason, upon no more than 90 and no fewer
than 60 days prior written notice to the Board of Directors and (ii) during the
second and third years following the Effective Date, (A) upon written notice to
the Board of Directors given at any time with immediate effect, for "Good
Reason" (as defined immediately below) or (B) upon no more than 90 and no fewer
than 60 days prior written notice to the Board of Directors given at any time,
for any reason or no reason, specifying in each case, whether resignation is
pursuant to subsection (A) or (B) above. The Executive shall have "Good

                                       8


<PAGE>





Reason" to terminate his employment with the Company upon the occurrence of
either of the following events:

                           (x) the Company should fail to continue to employ the
Executive during the Employment Term in a manner consistent with Section 3 and
in the same executive capacity with the Company in which the Executive was
employed by PanAmSat Corporation immediately prior to the Merger, with
materially the same duties and responsibilities with the Company that the
Executive had with PanAmSat Corporation immediately prior to the Merger;
provided, that the Executive shall be required prior to the effectiveness of a
constructive termination pursuant to this subsection (x) to have given the
Company twenty (20) days notice and an opportunity to cure such failure. Without
in any way limiting the right of the Executive to elect to terminate his
services under Section 7(d)(ii)(A), it is understood that any change in the
Executive's job description, offices, perquisites or place of employment by more
than 35 miles, any reduction in the number of officers or other employees or
diminishment in the overall management responsibility of officers and other
employees reporting directly to the Executive, any diminishment in the decision
making authority of the Executive shall each be a change in his duties and
responsibilities that will give the Executive the right to elect to terminate
his services under Section 7(d)(ii)(A); or


                                       9


<PAGE>





                           (y) the Company should reduce or fail to pay or award
to the Executive when due any Base Salary, Incentive Bonus or other amount
payable to the Executive or to provide the Executive with any benefits to which
the Executive is entitled.

                      (e) Discretionary Termination by the Company. Upon
delivery of written notice of termination of the Executive's employment for a
reason other than Material Breach, death or Disability from the Company to the
Executive, the Employment Period shall be deemed to have terminated 60 days
after the written notice is delivered to the Executive.
                           
                      (f) Continuation of Salary and Benefits. In the event the
Executive's employment terminates during the Employment Period as of result of
his death as set forth in paragraph 7(a), or as a result of the Executive's
Disability as set forth in paragraph 7(b), the Company shall pay to the
Executive or his estate, as the case may be, his Base Salary and any employee
benefits, including group medical benefits, to which he would otherwise be
entitled under this Agreement, for 12 months from the date of termination of
employment. (g) Termination Payment. If the Executive's employment terminates
during the Employment Term as a result of (i) termination by the Company in
accordance with paragraph (e) of this Section 7; or (ii) Resignation by the
Executive in accordance with paragraph (d)(i) or (ii)(A) of this Section 7,


                                       10

<PAGE>





the Executive shall be entitled to a Termination Payment from the Company and
the continuation of certain employee benefits. The term "Termination Payment"
shall mean an amount that is equal to 3 times the sum of (1) Salary (as defined
below), plus (2) the Applicable Bonus (as defined below). The term "Salary"
herein shall mean the annual cash compensation payable to the Executive by the
Company and/or, during the first year hereunder, by PanAmSat Corporation, and
the term "Applicable Bonus" shall mean the annual amount awarded or paid under
any incentive or bonus plan or program of the Company and/or, during the first
year hereunder, by PanAmSat Corporation and any additional amounts (such
aggregate amounts, the "Bonus") paid to the Executive by the Company and/or,
during the first year hereunder, by PanAmSat Corporation, during the fiscal year
ending immediately prior to the fiscal year in which the termination occurred
(excluding, however, the special bonus in lieu of stock option of $950,000 paid
to Executive in September of 1996 by PanAmSat Corporation), or the Bonus
scheduled to be paid to the Executive during the fiscal year in which the
termination occurs, prorated to the date of termination, whichever is greater.
The Termination Payment shall be due and payable ten (10) days after the
Executive is or has been terminated from, or terminates, his employment with the
Company. The Executive and his dependents also shall be entitled to participate,
for a period of three years following termination, in all employee

                                       11


<PAGE>





welfare benefit plans (as that term is defined in Section 3(1) of the Employee
Retirement Income Security Act of 1974, as amended), and to receive or
participate in all other benefit arrangements, policies or practice of the
Company to which and in which active executive employees are or shall be
entitled to receive or participate in during this period other than qualified
pension or profit sharing plans in which he would not legally be entitled to
participate.

                      (i) Vesting of Options. Upon termination of the
Executive's employment during the Employment Period for any reason other than as
a result of termination for Material Breach under Section 7(c) or Resignation by
the Executive under Section 7(d)(i) or (d)(ii)(B), all unvested Options granted
to Executive shall vest immediately and be exercisable for the remainder of
their original term. Upon termination of the Executive's employment for any
reason, all vested Options shall continue to be exercisable for their original
term. The provisions of this Section 7(i) shall survive the expiration of this
Agreement and shall be separately provided for in the relevant option agreement
with Executive provided in connection with the Option grant.
                           
                      (j) Registration; Stock Repurchase Rights. In the event
the Executive's employment with the Company terminates for any reason during the
Employment Term, the Executive may, by written notice to the Company, demand
that the Company register all or any portion of the Common Stock of


                                       12

<PAGE>





the Company held by him, beneficially or otherwise, and the Company shall
promptly (1) enter into a registration rights agreement (the "Registration
Rights Agreement") substantially similar to the amended and restated
registration rights agreement in the form of that attached as Exhibit F to the
Agreement and Plan of Merger; provided, that a demand registration pursuant to
such Registration Rights Agreement shall (i) cover a minimum of one-half of the
shares of Common Stock of the Company held, beneficially or otherwise, by the
Executive immediately following the Merger, and (ii) be effective for one demand
registration requested by the Executive during the first year after the Merger,
and (2) register said Common Stock in accordance with the provisions of the
Registration Rights Agreement; provided, that following any such demand, the
Company shall have the right, by written notice sent to the Executive within ten
(10) days of receipt of a Demand Notice (as defined in the Registration Rights
Agreement), to purchase at the Repurchase Price (as defined below) any or all
shares of Common Stock of the Company covered by the Demand Notice. The Company
shall purchase such shares from the Executive by making a lump sum payment to
the Executive (or his estate), within thirty (30) days of receiving the Demand
Notice. "Repurchase Price" means the average of the closing price of the Common
Stock for the thirty consecutive Trading Days (as defined below) ending the date
following the date on which the Company receives the


                                       13

<PAGE>





Demand Notice. A "Trading Day" shall be any day on which the principal national
securities exchange on which the Common Stock is admitted to trading or listed
is open.

                      (k) Termination Date. The date upon which Executive's
employment with the Company terminates shall constitute the "Termination Date."

                  8. Confidential Information.

                           The Executive agrees not to disclose, either
while in the Company's employ or at any time thereafter, to any person not
employed by the Company, or not engaged to render services to the Company, any
confidential information obtained by him while in the employ of the Company,
including, without limitation, information about any of the Company's finances,
costs, profits, markets, software, inventions, data lists, client lists,
operational methods, technical matters, pricing policies, business plans, or
customer or trade secrets; provided, however, that this provision shall not
preclude the Executive from use or disclosure of information which is in the
public domain or from disclosure required by law or court order (after notice to
the Company to permit it to contest the need for disclosure or to seek an
appropriate protective order).


                                       14


<PAGE>





                  9. Non-Competition.

                           (a) Competition. The Executive agrees that for a
period of three years after the Termination Date, the Executive will not,without
the prior written approval of the Board of Directors, participate in the
management of, be employed by or own any interest in any business enterprise
that engages in (A) the sale or lease of, or the provision of satellite services
via, transponder capacity on satellites operating in geostationary earth orbit
in the C-band, Ka-band and Ku-band frequencies for the transmission of video,
audio and data signals; and (B) the provision of telemetry, tracking and control
services for such satellites and for other satellites operating in geostationary
earth orbit in the C- band, Ka-band, Ku-band, L-band and UHF-band frequencies or
other frequency bands that may be utilized in the future; but in each case
excluding the sale or lease of transponder capacity and telemetry, tracking and
control services provided on or for any satellite that has both (x) multiple
(six or more) receive and transmit beams and (y) an on-board satellite payload
processor which can switch uplink signals in one beam to a downlink signal in
one of multiple beams; provided, however, that nothing in this Section 9(a)
shall prohibit the Executive from owning less than 5% of the outstanding equity
securities of any enterprise whose equity securities are publicly traded.
Notwithstanding the above, in the event the Executive's employment ends as a
result of Disability under


                                       15

<PAGE>





Section 7(b), the restrictions in this Section 9(a) shall continue only for the
period during which the Executive continues to receive salary and benefits from
the Company pursuant to this Agreement.
                           
                           (b) Interference. The Executive hereby agrees that
until such time as the restrictions contained in Section 9(a) lapse in
accordance with their terms, he will not intentionally interfere with the
Company's relationship with, or endeavor to entice away from the Company, any
employee, person, firm, corporation, or other business organization who or which
was an employee, customer or supplier of, or maintained a business relationship
with, any business of the Company which was conducted at any time prior to the
Termination Date. Nothing in this Section 9(b) prohibits the Executive from
employing or doing business with any employee, person, firm, corporation or
other business organization who, by his or its own choice, seeks to be employed
or do business with the Executive.
                           
                           (c) The Executive expressly acknowledges and
understands that the remedy of law for any breach by him of this Section 9 will
be inadequate, and that the damages flowing from such breach are not readily
susceptible to being measured in monetary terms. Accordingly, it is acknowledged
that upon the Executive's violation of any provision of this Section 9, the
Company shall be entitled to immediate injunctive relief and may obtain a
temporary order restraining


                                       16

<PAGE>





any threatened or further breach. Nothing in this Section 9 shall be deemed to
limit the Company's remedies at law or in equity for any breach by the Executive
of any of the provisions of this Section 9 which may be pursued or availed of by
the Company.

                           (d) If following termination of the Executive's
employment any of the restrictions pursuant to this Section 9 shall for any
reason be held by to be excessively broad as to duration, geographical scope,
activity or subject, such restrictions shall be construed so as to thereafter be
limited or reduced to the extent required to be enforceable in accordance with
applicable law; it being understood and agreed that by execution of this
Agreement the parties hereto regard such restrictions as reasonable and
compatible with their respective rights.

                  10. Excise Tax. In the event that the Termination Payment or
any other amounts payable to the Executive, his designated beneficiary or his
dependents under this Agreement or under any plan, program or policy of the
Company, or any benefits provided to Executive or his dependents under this
Agreement or under any option or other plan, program or policy of the Company,
should become subject to the excise tax imposed under Section 4999 of the
Internal Revenue Code or any similar tax or assessment (collectively, "Excise
Taxes"), the Company shall pay to the Executive, his designated beneficiary

                                       17


<PAGE>





or his dependents, as the case may be, on demand, the amount (the "Excise Tax
Reimbursement Amount"), necessary fully to reimburse the Executive, his
designated beneficiary or his dependents for (i) all Excise Taxes that may be
imposed on the Executive, his designated beneficiary or his dependents and (ii)
any and all income and other taxes, including additional Excise Taxes, that may
be imposed on the Executive, his designated beneficiary or his dependents in
respect of any of the amounts to be paid to the Executive, his designated
beneficiary or his dependents under clause (i) above or under this clause (ii).
The determination of the Excise Tax Reimbursement Amount shall initially be made
by the accounting firm that is serving as the Company's independent public
accountants immediately prior to the date of termination of the Executive's
employment, or, if such accounting firm is no longer in existence, by its
successor. All costs and expenses of such accounting firm in connection with
making such determination shall be paid by the Company. If it is subsequently
determined (as a result of an assessment of additional Excise Taxes by the
Internal Revenue Service or otherwise) that the Excise Tax Reimbursement Amount
is not sufficient fully to reimburse the Executive, his designated beneficiary
or his dependents as contemplated above, the Company shall pay to the Executive,
his designated beneficiary or his dependents, as the case may be, on demand, the
amount (the "Additional Excise Tax Reimbursement Amount") necessary


                                       18

<PAGE>





fully to reimburse the Executive, his designated beneficiary or his dependents
for (i) any and all additional Excise Taxes, income taxes and other taxes that
may be imposed on the Executive, his designated beneficiary or his dependents,
(ii) any and all interest, fines and penalties that may be imposed on the
Executive, his designated beneficiary or his dependents in connection with any
such additional Excise Taxes, income taxes or other taxes, and (iii) any and all
income and other taxes, including additional Excise Taxes, that may be imposed
on the Executive, his designated beneficiary or his dependents in respect of any
of the amounts to be paid to Executive, his designated beneficiary or his
dependents under clause (i) or (ii) above or under this clause (iii). If it is
subsequently determined that the Executive has received a sum greater than
necessary to pay any such Excise Taxes, the Executive shall promptly return such
overage to the Company. The purpose of this paragraph 10 is to place the
Executive, his designated beneficiary and his dependents in the same position on
an after-tax basis that each of them would have been in if the Termination
Payment and all other amounts payable to the Executive, his designated
beneficiary or his dependents under this Agreement or under any plan, program or
policy of the Company, and all benefits provided to the Executive or his
dependents under this Agreement or under any plan, program or

                                       19
