ORLANDO — The White House announced April 22 its intent to nominate an ocean scientist to be the next administrator of the National Oceanic and Atmospheric Administration, and a Defense Department official to be NASA’s next chief financial officer. The White House said that it will nominate Rick Spinrad to be administrator of NOAA and

KENNEDY SPACE CENTER, Fla. — SpaceX launched a Crew Dragon spacecraft carrying four astronauts from three nations April 23 as the commercial crew program moves firmly into operations. The Falcon 9 rocket lifted off from Launch Complex 39A here at 5:49 a.m. Eastern on the Crew-2 mission. The Crew Dragon spacecraft separated from the Falcon

The prototype proton therapy system will use MRI to visualize tumour motion in real time during treatments. (Courtesy: B Oborn) Proton therapy is an advanced cancer treatment technique that delivers highly targeted dose to the tumour while sparing surrounding normal tissue, enabled by the finite range of the proton beam. This precision targeting, however, is

“Climate change” is changing. There has been a growing push by scientists, environmental advocates and others to refer to the Earth’s changing climate as a “climate crisis” or even “climate emergency” to better reflect the severity of the problem and the urgency to take action to mitigate the worst of its effects. On April 12,

Lamborn: “Every dollar spent on moving Space Command is a wasted dollar that could be spent on enhancing space capabilities” WASHINGTON — U.S. Space Command has close ties to other military space organizations in Colorado, but if it has to move to Alabama it could continue to do its job without major disruption, Gen. James

Visualizing subcellular structures deep inside the brains of living animals could improve our understanding of how neurons function in their native environment. Thanks to an improved super-resolution microscopy technique developed at Yale University, that dream is now one step closer to reality. Writing in Optica, the researchers combined stimulated emission depletion (STED) microscopy with two-photon

The Space Development Agency needs “affordable” optical terminals that can be mass produced WASHINGTON — Each of the satellites in the Space Development Agency’s mesh network known as the Transport Layer could have as many as five laser links so they can talk to other satellites, airplanes, ships and ground stations.  Realizing that goal will

By Allison Kubo Hutchison Graphs are the bread and butter of scientists. We love them. Lines plots, bar graphs, line plots. Visual representations of data are the default on science. However, sonification, the transformation of data into sound rather than images has been gaining interest. One reason is that our ears actually have better time

WASHINGTON — Six months after including it on the team that was a NASA technology contract, Lockheed Martin has quietly dropped in-space transportation company Momentus from that project. Lockheed was one of 14 companies that received Tipping Point awards from NASA in October 2020 to demonstrate key technologies needed for sustainable lunar exploration. Lockheed’s award

Unexpected motion: disorder mixes excited states, which allows transport to occur. (Courtesy: iStock_piranka) Under the right conditions, the transport of electrical charges through wires with nanometre-scale thicknesses could become more efficient as disorder in the nanowire increases. This counterintuitive behaviour could be possible following a theoretical discovery made by physicists in Italy and Mexico. Nahum

WASHINGTON — The next commercial crew mission to the International Space Station passed its final review before its scheduled April 22 launch, with weather the only major issue. At an April 20 briefing, NASA said the Crew-2 mission passed its launch readiness review, the final major review before launch. That allows NASA and SpaceX to

WASHINGTON — The successful flight of NASA’s Ingenuity helicopter on Mars paves the way for its use on future missions, agency officials said, but exactly when and how remain to be determined. At a press conference April 19, project officials said Ingenuity’s first flight, also the first powered flight by an aircraft on another world,

Transcranial ultrafast ultrasound localization microscopy of deep brain vessels in a human patient. (Courtesy: Alexandre Dizeux/Physics for Medicine Paris) Researchers at the laboratory Physics for Medicine Paris have performed the first microscopic mapping of the vascular network in the human brain. The team used transcranial ultrafast ultrasound localization microscopy (ULM) of intravenously injected microbubbles to

NRO’s Pete Muend: ‘One of the things that we are moving out on is the potential to purchase commercial radar imagery’ WASHINGTON — The National Reconnaissance Office plans to sign new deals with commercial providers of satellite radar imagery as the agency looks to better understand the capabilities of the private sector, a senior NRO

WASHINGTON — Boeing said April 17 that the next test flight of its CST-100 Starliner commercial crew vehicle won’t take place until at least August, confirming a lengthy delay widely expected because of the schedule of other launches and International Space Station missions. In a statement, Boeing said that the company and NASA are projecting

WASHINGTON — NASA now plans to attempt a first flight of the Mars helicopter Ingenuity early April 19 after finding a workaround to a software problem that delayed the flight earlier this month. The agency announced April 17 that the first flight of the 1.8-kilogram helicopter will take place at 3:31 a.m. Eastern. Images and

Updated 8 p.m. Eastern with comments by Beyer and Bridenstine. WASHINGTON — The White House announced April 16 it will nominate former astronaut Pam Melroy to be NASA’s deputy administrator. Melroy’s nomination was one of eight the White House announced to fill positions across the government. The position will require confirmation by the Senate. Melroy
