Astronauts finished unfurling a new pair of solar panels outside the International Space Station on Friday, making their third spacewalk in just over a week.
NASA's Shane Kimbrough and France's Thomas Pesquet successfully installed the second in a series of powerful solar wings that should keep the space station running the rest of this decade, as space tourism ramps up with visitors beginning in the fall.
NOAA to replace GOES-17 satellite ahead of schedule

SAN FRANCISCO – The National Oceanic and Atmospheric Administration announced plans June 25 to move its geostationary weather satellite scheduled to launch in December into an operational role “as soon as possible.”
NOAA’s Geostationary Operational Environmental Satellite, GOES-T, will replace the GOES-17 satellite in the GOES West position because of problems with the satellite’s main instrument, the Advanced Baseline Imager (ABI), according to a NOAA news release.

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.
Military building an appetite for commercial space services

The U.S. Space Force is eager to tap into the vibrant commercial market for space services enabled by increasingly capable small satellites and cheaper access to orbit.
Commercial services of particular interest to the military include imagery, analytics, weather data and broadband from low-Earth orbit constellations.
Report backs NASA proposal to change astronaut radiation exposure limits

WASHINGTON — A National Academies committee has endorsed a NASA proposal to change the radiation exposure limits the agency sets for its astronauts but cautioned that the revised limit is still insufficient for human Mars missions.
Connecting the Dots | Space after SPACs: Industry could be on the verge of new investment era
Friday, 25 June 2021 14:57 Write a comment
The SPAC investment trend injecting billions of dollars into early-stage space startups appears to have peaked, but in its wake could be larger capital infusions from institutional investors with deeper pockets.
Seven space companies plan to reap more than $3 billion in total later this year by merging with a SPAC — blank check firms that raise money on a public market before combining with businesses to fast-track investor exits.

Mars colonists are going to wish they had an atmosphere above them
Friday, 25 June 2021 11:10 Write a comment
There will be all sorts of risks for any future colonists on Mars, such as extreme weather and temperatures, radiation, and the human physiological problems associated with living in with decreased gravity. But another issue is that colonists on Mars will have to be on a constant lookout above their heads.
While Mars and Earth are both hit by space debris regularly—dust, small rocks and bigger meteoroids—on our planet, meteors usually vaporize in the atmosphere.
"On Mars however, with a surface pressure one 100th that of the Earth, the impactors generally make it to the surface," says the team from the HiRISE camera on the Mars Reconnaissance Orbiter (MRO).
Virgin Galactic cleared to fly customers on SpaceShipTwo

Study Looks More Closely at Mars' Underground Water Signals
Friday, 25 June 2021 05:24 Write a comment
A new paper finds more radar signals suggesting the presence of subsurface 'lakes,' but many are in areas too cold for water to remain liquid.
In 2018, scientists working with data from ESA's (the European Space Agency's) Mars Express orbiter announced a surprising discovery: Signals from a radar instrument reflected off the Red Planet's south pole appeared to reveal a liquid subsurface la Collection of starshade research helps advance exoplanet imaging by space telescopes

The open access Journal of Astronomical Telescopes, Instruments, and Systems (JATIS) has published a special section on the latest science, engineering, research, and programmatic advances of starshades, the starlight-suppression technology integral to extra-solar and exoplanet detection.
Section topics range from starshade programs and missions, to various aspects of related technologies, AiRANACULU wins second NASA contract for advanced space communications system

AiRANACULUS, a private, Massachusetts-based technology company providing early stage research, development, prototyping and consulting services, announced it has been awarded a second NASA Small Business Innovation Research contract for development of an advanced space communications system to support upcoming missions to the Moon and Mars.
Under the new contract, AiRANACULUS will develop NASA to send mannequins to moon to prepare for crewed missions

NASA's upcoming Artemis I mission to the moon, planned for later this year, won't have a human crew, but the space agency is preparing three inanimate occupants of the Orion capsule to measure radiation and vibrations.
The Artemis I "crew" members, mannikins, will help NASA test radiation, vibration and impacts from landing before the space agency plans to send astronauts in an Orion ca
