Sierra Space provides integration services for nuclear propulsion system for DARPA's Draco Program
Write a comment
Sierra Space, the new commercial space subsidiary of global aerospace and national security leader Sierra Nevada Corporation (SNC), will supply the propulsion components and integration services for a Nuclear Thermal Propulsion (NTP) system under a recent contract with General Atomics Electromagnetic Systems (GA-EMS). GA-EMS and Sierra Space will develop and demonstrate an on-orbit NTP system fo Astronauts unfurl 60-foot-long space station solar array

Two astronauts concluded a spacewalk Friday outside the International Space Station and installed a second of six new solar arrays that will boost the orbiting laboratory's electrical power supply.
Shane Kimbrough and Thomas Pesquet exited the space station about 8 a.m. EDT. They successfully mounted and rolled out a 60-foot-long solar array, known as iROSA or International Space Statio Researchers aim to move an asteroid

An asteroid strike on Earth could be prevented by new technology launching into space this year, involving a Queen's University Belfast scientist.
Professor Alan Fitzsimmons from the Astrophysics Research Centre at Queen's is playing a role in two space missions that will measure how hard it is to deflect an asteroid. He will be telling people about it in an online public talk on World Ast Virgin Galactic receives approval from FAA for Full Commercial Launch License

Virgin Galactic has announced that the Federal Aviation Administration has updated the Company's existing commercial space transportation operator license to allow the spaceline to fly customers to space.
The Company also announced that it has completed an extensive review of data gathered from its May 22 test flight and confirmed that the flight performed well against all flight objective Getting a robot to take a selfie on Mars

Ever wondered how Mars rovers take a selfie? Color video from NASA's Perseverance shows how the rover captured the historic April 6, 2021, image of itself beside the Ingenuity Mars Helicopter. As a bonus, the rover's entry, descent, and landing microphone captured the sound of the arm's motors whirring during the process.
Selfies allow engineers to check wear and tear on the rover. But the AFRL leaps forward in NTS-3 spacecraft development

The Air Force Research Laboratory is excited to announce that the Navigation Technology Satellite-3 (NTS-3) satellite navigation program is closer in the development of the spacecraft for its in-space demonstration, thanks to the delivery of its bus that will carry it to space in 2023.
In 2019, the U.S. Air Force designated NTS-3 as one of three Vanguard programs, which are priority initia Giant comet found in outer solar system by Dark Energy Survey
Write a comment
A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It i Unique use of ESA spacecraft ‘housekeeping’ data reveals cosmic ray behaviour
Write a comment
Using data originally gathered for spacecraft ‘housekeeping’ aboard ESA’s Rosetta and Mars Express missions, scientists have revealed how intense bursts of high-energy radiation, known as cosmic rays, behave at Mars and throughout the inner Solar System.
NASA completes additional tests to diagnose computer problem on Hubble space telescope
Write a comment
NASA is continuing to diagnose a problem with the payload computer on the Hubble Space Telescope after completing another set of tests on June 23 and 24. The payload computer halted on June 13 and the spacecraft stopped collecting science data. The telescope itself and its science instruments remain in good health and are currently in a safe configuration.
The spacecraft has two payload computers, one of which serves as a backup, that are located on the Science Instrument and Command and Data Handling (SI C&DH) unit. There are various pieces of hardware which make up both payload computers, including but not limited to:
- a Central Processing Module (CPM), which processes the commands that coordinate and control the science instruments
- a Standard Interface (STINT), which bridges communications between the computer's CPM and other components
- a communications bus, which contains lines that pass signals and data between hardware
- and one active memory module, which stores operational commands to the instruments. There are three additional modules which serve as backups.
Additional tests performed on June 23 and 24 included turning on the backup computer for the first time in space.
