NASA’s Tiny BurstCube Mission Launches to Study Cosmic Blasts - NASA Science
This approach is part of a new way of understanding the cosmos called multimessenger astronomy.The collisions that create short gamma-ray bursts also produce heavy elements like gold and iodine, an essential ingredient for life as we know it.Currently, the only joint observation of gravitational waves and light from the same event – called GW170817 – was in 2017. It was a watershed moment in multimessenger astronomy, and the scientific community has been hoping and preparing for additional concurrent discoveries since.“BurstCube’s detectors are angled to allow us to detect and localize events over a wide area of the sky,” said Israel Martinez, research scientist and BurstCube team member at the University of Maryland, College Park and Goddard. “Our current gamma-ray missions can only see about 70% of the sky at any moment because Earth blocks their view. Increasing our coverage with satellites like BurstCube improves the odds we’ll catch more bursts coincident with gravitational wave detections.”BurstCube’s main instrument detects gamma rays with energies ranging from 50,000 to 1 million electron volts. (For comparison, visible light ranges between 2 and 3 electron volts.)When a gamma ray enters one of BurstCube’s four detectors, it encounters a cesium iodide layer called a scintillator, which converts it into visible light. The light then enters another layer, an array of 116 silicon photomultipliers, that converts it into a pulse of electrons, which is what BurstCube measures. For each gamma ray, the team sees one pulse in the instrument readout that provides the precise arrival time and energy. The angled detectors inform the team of the general direction of the event.BurstCube belongs to a class of spacecraft called CubeSats. These small satellites come in a range of standard sizes based on a cube measuring 10 centimeters (3.9 inches) across.

About Rapid Response
Imagery available through Rapid Response and LANCE are available freely and may be reproduced for any purpose. We ask that you acknowledge Rapid Response, visit the Citation Policy and Disclaimer page for the full acknowledgement.
Expedited Processing
To make imagery available in less than 3 hours, expedited Level 0 data are processed using predicted attitude and ephemeris data. In some cases, this can result in significant differences exist between the near real-time LANCE products and the standard products. Data products available through LANCE should not be regarded as science quality and should not be used for quantitative science analyses. Nonetheless, all LANCE products have been reviewed by members of the instrument Science Teams and have been approved for applications purposes.
Background
The Rapid Response system was originally developed in 2001 to provide near real-time data and imagery from the MODIS instrument aboard the Terra Satellite, to meet the needs of the U.S. Forest Service (USFS), the National Interagency Fire Center (NIFC) and other federal and state users. Rapid Response, then known as the MODIS Land Rapid Response System, was made possible through the collaboration between staff of NASA's Goddard Space Flight Center, the Department of Geographical Sciences at the University of Maryland and the USFS Remote Sensing Applications Center (RSAC). By 2007, the Rapid Response System was producing data globally and had incorporated data and imagery from the MODIS instrument on the Aqua satellite. As this rapid response image and information provision capability became more visible, news organizations began requesting custom geo-referenced images for large newsworthy events.

NASA’s Perseverance puts its robotic arm to work around a rocky outcrop called “Skinner Ridge” in a set of images captured in June and July 2022 by the rover’s Mastcam-Z camera system. SHERLOC is mounted on the end of the arm.
NASA/JPL-Caltech/ASU/MSSS

UPDATE, Mar. 5, 2024: Engineers for NASA’s Perseverance Mars rover have made progress addressing the issue affecting the SHERLOC instrument’s Autofocus Context Imager (ACI), but at present the instrument’s Raman spectroscopic capability remains offline.
To better understand the issue with the mechanism and move the ACI cover to a fully open position, the engineering team has tried different actions to move the cover, including heating, increasing drive torque, commanding a rocking motion, and even commanding the rover’s drill to perform its percussive action in free space (not against a rock). The cumulative effects of these actions resulted in the cover moving substantially toward the fully open position.
While the team has concluded that the cover and autofocus mechanism will not return to being fully operational, they continue to work on opening the cover even further and on focusing the optics in a fixed position. The same mechanism that moves the cover also controls the focus of the ACI.

Imagine the Universe!
She knew she loved teaching, so she began with what she knew best: physics and math. But in a surprising turn, after a couple of years of teaching Jean realized that going back to school to study physics would help her become the best teacher she could be. Columbia University welcomed her. It was hard work, but once again physics was fascinating and fun.
The New Physicist

Reflection Grating Spectrometer for XMM

In a short time, her interest in teaching physics started to take a back seat to physics research. For her graduate work, Jean chose to study astrophysics - "a wonderful field with wide open discovery space." And because it blends lab work and theory, she chose experimental astrophysics, where "you get to build things and walk around with a wrench in your back pocket. You apply physics every day, trying to make instruments and understand how they work. Then you get to analyze the data from those instruments."
The XMM-Newton Observatory's high-resolution Reflection Grating Spectrometer (RGS) (on right) was the best project for her because of its development timeline: she could be involved in building the instrument and still be there when the data arrived from space. The RGS is a European Space Agency project with some contributions from US institutions.
Jean was able to help build and test it at Columbia before it was integrated into the spacecraft. She earned her PhD working on the development and characterization of the RGS and the use of it and other spectrometers to study low mass x-ray binaries. (Characterization is the detailed description of the way an instrument works. It's extremely important because scientists must understand the instrument's contribution to the raw data they see and be able to separate its effects from the light of real astrophysical objects.) The XMM-Newton Observatory launched in 1999, and then Jean had the opportunity to characterize it while in orbit. She completed the experience by studying astrophysical objects using RGS data.
Invaluable Experience

Experimental physicists are often divided into instrumentalists and data analysts. The instrumentalists build the satellites and the data analysts use the data from them.

Sounds of Mars from Perseverance Rover
This image was taken during the first drive of NASA’s Perseverance rover on Mars on March 4, 2021. Perseverance landed on Feb. 18, 2021, and the team has been spending the weeks since landing checking out the rover to prepare for surface operations. 

First Audio Recording of Sounds on Mars 

This recording was made by the SuperCam instrument on NASA’s Perseverance Mars rover on Feb. 19, 2021, just about 18 hours after landing on the mission’s first sol or Martian day. The rover’s mast, holding the microphone, was still stowed on Perseverance’s deck, and so the sound is muffled, a little like the sound one hears listening to a seashell or having a hand cupped over the ear. Just a little wind can be heard. Credit: NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-Supaero

Perseverance Rover’s SuperCam Records Wind on Mars

This recording was made on Feb. 22, 2021, on the fourth sol (Martian day) by the SuperCam instrument on NASA’s Perseverance rover after deployment of the rover’s mast. It provides a different overall sound than the SuperCam audio recording from the mission’s first sol. Some wind can be heard, especially around 20 seconds into the recording. Rover background sounds have been removed. Credit: NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-Supaero

First Acoustic Recording of Laser Shots on Mars

This is the first acoustic recording of laser impacts on a rock target on Mars from March 2, 2021, the 12th sol (Martian day) from Perseverance’s SuperCam instrument. The sounds of 30 impacts are heard, some slightly louder than others.
