NASA Shuttle Radar Topography Mission Global 3 arc second Number NetCDF V003

The Land Processes Distributed Active Archive Center (LP DAAC) is responsible for the archive and distribution of NASA Making Earth System Data Records for Use in Research Environments ([MEaSUREs](https://earthdata.nasa.gov/about/competitive-programs/measures)) SRTM, which includes the global 3 arc second (~90 meter) product. The 3 arc second data was derived from the 1 arc second using averaging methods. (See Figure 3 in the User Guide) The NASA SRTM data sets result from a collaborative effort by the National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA - previously known as the National Imagery and Mapping Agency, or NIMA), as well as the participation of the German and Italian space agencies. This collaboration aims to generate a near-global digital elevation model (DEM) of Earth using radar interferometry. SRTM was the primary (and virtually only) payload on the STS-99 mission of the Space Shuttle Endeavour, which launched February 11, 2000 and flew for 11 days.The SRTM swaths extended from ~30 degrees off-nadir to ~58 degrees off-nadir from an altitude of 233 kilometers (km), creating swaths ~225 km wide, and consisted of all land between 60° N and 56° S latitude to account for 80% of Earth's total landmass. The SRTMGL3 data were generated from [SRTM1GL](https://doi.org/10.5067/MEaSUREs/SRTM/SRTMGL1.003) data that fall within that tile. These elevation files use the extension ".HGT", meaning height (such as N37W105.SRTMGL3.HGT). The primary goal of creating the Version 3 data was to eliminate gaps, or voids, that were present in earlier versions of SRTM data. In areas with limited data, existing topographical data were used to supplement the SRTM data to fill the voids. The source of each elevation pixel is identified in the corresponding [SRTMGL3N](https://doi.org/10.5067/MEaSUREs/SRTM/SRTMGL3N.003) product (such as N37W105.SRTMGL3N.NUM).The global 3 arc second SRTM product is also available in NetCDF4 format as the SRTMGL3_NC dataset with the source of each elevation pixel in the corresponding SRTMGL3_NUMNC product.Known Issues* Known issues in the NASA SRTM are described in the following publication: * Rodriguez, E., C.

Laser frequency stabilization and stray light issues for LISA and other future multi-spacecraft missions Project

"The Laser Interferometer Space Antenna (LISA) is a joint NASA/ESA project which will use laser interferometry between drag-free proof masses to measure gravitational waves from many galactic and cosmological sources. The same interferometer technology is also the key to future multi-spacecraft missions such as multi-aperture telescope missions. These missions could include several spacecraft all separated by potentially 10s of km, flying in a fixed formation with sub-wavelength variations in their distances. These multi-aperture or distributed aperture telescopes will revolutionize the angular resolution in the infrared, optical, and even X-ray band. This proposal addresses two components which are both critical to these missions. The first component introduces a new technique to stabilize the laser frequency to an optical reference cavity. Laser frequency noise will be the limiting factor for most of the distributed aperture telescope missions; in contrast, LISA can trade frequency noise against ranging precision. This new technique is based on heterodyne interferometry which is also used to measure changes in the distances between the spacecraft. Because of this similarity, this technology can easily be integrated into the payload. It requires the same photo detectors and digital signal processing systems that are used for the interferometry. It utilizes to a large degree existing components, reducing R&D time and cost for all interferometric space missions. We have already started initial proof of principle experiments and have reached already a performance remarkably close to the performance of the standard and long time-favored modulation/demodulation technique. Now we propose to study this technique in more detail, study the limiting noise sources experimentally and theoretically, and push it to the limitations of the reference cavity itself. The expected final fractional frequency noise should be better than 0.01ppt for measurement times of a 1000s. This

Single cell transcriptional profiling of spleens from mice flown on Rodent Research Reference Mission-2 (RRRM-2)

In the Rodent Research Reference Mission (RRRM-2), forty female C57BL/6NTac mice were flown on the International Space Station. To assess differences in outcomes due to age, twenty 12 week-old and twenty 29 week-old mice were flown, respectively. To directly assess spaceflight effects, half of the young and old mice (10 old, 10 young) were sacrificed on-orbit after 55-58 days (ISS Terminal, ISS-T), while the other half (10 old, 10 young) were returned live to Earth after 32 days and allowed to recover for 24 days (Live Animal Return, LAR) before sacrifice. ISS-T and LAR mice were the same age at sacrifice. Both the ISS-T and LAR animals had independent ground controls (10 mice per group housed in flight hardware in matched environmental conditions), basal controls (10 mice per group sacrificed 2 days before launch), and vivarium controls (10 mice per group housed within standard vivarium habitats). Thus RRRM-2 included a total of 160 mice. This study includes single cell transcriptional profiling data from the spleens from 4 young LAR flight animals, 4 old LAR flight animals, 4 young LAR ground control animals, and 4 old LAR ground control animals.

Transcriptional profiling of thymus from mice flown on the RR-23 mission

The objective of the Rodent Research-23 missions (RR-23) was to better understand the effects of spaceflight on the eyes, specifically on the structure and function of the arteries, veins, and lymphatic vessels that are needed to maintain vision. To this end, twenty male, C57BL/6J, 16-17 weeks old mice were delivered to the ISS on SpaceX-21 in a single transporter, transferred to two rodent habitats, and maintained in microgravity for 38 days. Flight mice were then returned to Earth alive (Jan 13th, 2021). After splashdown in the Atlantic Ocean, mice were transported to Kennedy Space Center via helicopter. The 20 Flight, 20 Habitat Ground Control (HGC), and 20 Vivarium Ground Control (VGC) mice were removed from Rodent Transporters (Flight and HGC) or vivarium cages (VGC), placed into shipping containers, and flown to Texas A and M University. There, mice underwent post flight procedures, before euthanasia and tissue collection. Flight, HGC and VGC animals were euthanized and dissected on Jan 14th, 17th or 20th of 2021, respectively. Thymus tissues were preserved by immersion in liquid nitrogen and stored at -80 ˚C until RNA was extracted, and libraries generated and sequenced (target 60 M clusters per sample, PE 150 bp). This dataset features 9 samples from the Flight group, 9 samples from the HGC group, and 9 samples from the VGC group. A technical replicate is included for one sample in each group. These consist of an independent library preparation for a single RNA extraction.
