Rare giant explosions on sun's surface could help NASA find out what we need to live on Mars
Tuesday, 30 April 2024 () NASA is preparing for an "unprecedented opportunity" to study how solar storms and radiation could affect future astronauts on Mars.
Mars, often dubbed the "red planet," has once again intrigued scientists with a new discovery. NASA's Perseverance rover, tirelessly exploring Mars' Jezero Crater since early 2021, has stumbled upon a peculiar sight: thousands of white rocks scattered across the crater's surface. Recent images transmitted by the rover reveal over 4,000 light-toned pebble-sized rocks strewn throughout the crater floor. "These rocks are highly unusual, and we're actively working to unravel their origins," remarked Candice Bedford, a planetary scientist at Purdue University and member of the Mars 2020 science team, speaking at the Lunar and Planetary Science Conference (LPSC) last month. Concurrently, NASA is wrapping up an architectural review of its Mars Sample Return (MSR) program, which aims to retrieve Martian rocks for detailed analysis back on Earth.

Astronomers Witness , Merger of 2 Black Holes, From the 'Cosmic Dawn'.
'The Independent' reports that NASA's
Webb Space Telescope has made the most
distant detection of merging black holes. .
Two gigantic black holes and the galaxies that they stood
at the center of merged together just 740 million years
after the universe was formed in the Big Bang.
One of the black holes is a staggering 50 million
times larger than our Sun, and the other
is believed to be a similar gigantic size. .
Astronomers have long wondered how supermassive black holes are so big. .
Lead author Hannah Ubler of the University of Cambridge
says the findings suggest that mergers like this ancient
example show how black holes are able to grow so rapidly.
According to Ubler, the latest Webb
discovery also suggests that black holes
have been merging since the "cosmic dawn.".

have been shaping
the evolution of galaxies

In 2021, NASA launched Webb, intended
to replace the Hubble Space Telescope.
Webb is the largest and most powerful
observatory ever launched into space. .

Contractor Warns of , Potential Catastrophe if NASA , Goes Ahead With Scheduled Launch.
IEN reports that a NASA contractor has publicly
urged the space agency to reconsider an
upcoming launch, warning it could end in disaster.
The news comes after the initial launch
of Boeing's Starliner was scrapped as
the result of a leaky valve just last week. .

The company issued a press release
warning that a second launch
attempt could end in catastrophe. .
The statement from ValveTech
President Erin Faville called for NASA
to re-double safety checks and protocols. .
The failed launch last week would have been
the first human space flight for Boeing but was
scrubbed after a faulty valve was discovered. .
The Associated Press reported that the fluttering oxygen
pressure-relief valve on United Launch Alliance’s Atlas
rocket may have exceeded its 200,000 lifetime cycles. .
The ValveTech statement questions how
NASA, Aerojet and Boeing could have... .
... "qualified this valve for the mission
without proper supporting data or
previous history or legacy information.".
According to ValveTech, this , "goes against aerospace-industry
qualification protocols established by NASA."

Boeing called off its first astronaut launch, ferrying two NASA test pilots to the International Space Station, because of a valve problem on its Starliner capsule. But if engineers find a solution quickly, another countdown could be expected in the next 24-hours.
