Maritime Launch Services Inc. (NEO: MAXQ) (MLSI) and Reaction Dynamics (RDX) are pleased to announce that they have signed a letter of intent to conduct launches from Spaceport Nova Scotia, expected to begin in 2023. These launches will provide the country sovereign launch capabilities and add Canada to the short list of "Launching States."

One of the prime objectives of the Perseverance mission is to collect a diverse cache of rock samples for eventual return to Earth. Among the highest priority rocks to sample are those that make up the well-preserved delta located on the western side of Jezero crater.
This delta was one of the key attributes that made this landing site so appealing for the search for ancient Martian life. DARPA seeks proposals leading to in-space demonstration of nuclear thermal rocket

DARPA is seeking proposals for Phases 2 and 3 of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program for the design, development, fabrication, and assembly of a nuclear thermal rocket engine. The goal is to execute an in-space flight demonstration of nuclear thermal propulsion in fiscal year 2026.
The overall objective of DRACO is to enable time-critical missions over va After ISS command change, NASA's Crew-3 prepares to undock for trip home

NASA's Crew-3 astronauts are preparing to undock from the International Space Station on Thursday after a six-month stay at the orbital outpost.
Raja Chari, Kayla Barron and Tom Marshburn of NASA, along with Matthias Maurer of Germany, are expected to board their Dragon spacecraft and close the hatch at 11:20 p.m. EDT, ahead of undocking from the ISS for the trip back to Earth.

We have cleared the "Greenheugh pediment" and the mix of sandy, steep, and rough terrain that challenged our drives up and down it. However, we are finding that as we make our way up Mount Sharp along a new route, some of the same driving gremlins are with us.
Yesterday's drive made it just about all the way to its endpoint, but Curiosity encountered higher than expected tilts as she attem Kacific launches all-in-one CommsBox for disaster relief

Blown by wind across continents and oceans, dust does more than make skies hazy, congest lungs, and leave a film on windshields. Also known as mineral dust or desert dust, it can influence weather, hasten snowmelt, and fertilize plants on land and in the ocean.

Entrusted by CAS President Hou Jianguo, Zhang Yaping, vice-president of New study reveals the effect of extended space flight on astronauts' brains

Long-duration space flight alters fluid-filled spaces along veins and arteries in the brain, according to new research from Oregon Health & Science University and scientists across the country.
The study published today in the journal Scientific Reports.
"These findings have important implications as we continue space exploration," said senior author Juan Piantino, M.D., assistant professor of pediatrics (neurology) in the OHSU School of Medicine. "It also forces you to think about some basic fundamental questions of science and how life evolved here on Earth."
The research involved imaging the brains of 15 astronauts before and after extended tours of duty on the International Space Station.
Researchers used magnetic resonance imaging to measure perivascular space—or the space around blood vessels—in the brains of astronauts prior to their launch and again immediately after their return. They also took MRI measurements again at one, three and six months after they had returned. Astronauts' images were compared with those taken of the same perivascular space in the brains of 16 Earth-bound control subjects.
Comparing before and after images, they found an increase in the perivascular spaces within the brains of first-time astronauts, but no difference among astronauts who previously served aboard the space station orbiting earth.

The Laser Interferometer Space Antenna reaches a crucial milestone
Wednesday, 04 May 2022 19:00 Write a comment
LISA, the Laser Interferometer Space Antenna, has reached an important milestone: it has passed the comprehensive "Mission Formulation Review" (MFR) and now enters the next phase of development. The review team, consisting of experts from ESA, NASA, the scientific community and industry, identified no showstoppers and confirmed that LISA has successfully reached a maturity sufficient to proceed to the next stage of development.
The MFR confirms the feasibility of the LISA mission and identifies a clear path of technology developments needed to reach the next major milestone: the mission adoption. The MFR is a checkpoint to ensure that the technology and planning for LISA is sufficiently mature; this is a prerequisite for mission development to continue. In an ESA mission lifetime cycle, the MFR is the formal end of Phase A (mission feasibility). LISA now enters Phase B1, which is focused on the preliminary definition of the mission.
"LISA is well underway. We are now entering phase B1, during which we do more detailed design work to establish the complete set of mission requirements and the verifications approach," says Prof. Karsten Danzmann, lead of the LISA Consortium.
