SpaceX And ISS Astronauts Set Record For Most Humans In Earth Orbit

Published

on


The number of astronauts in space has reached a new high. As many as 19 humans are currently in the low-Earth orbit at different locations. The bunch of travellers is composed of astronauts from NASA, SpaceX and those launched by China to its Tiangong Space Station. Notably, this is the highest number of humans in space at once.

The first and foremost is the International Space Station (ISS) with the biggest crew of 12 astronauts. The number was bumped up with the arrival of NASA’s Don Pettit and Aleksey Ovchinin with Ivan Vagner from Russian space agency, Roscosmos.

They arrived at the space station at 1:02 am IST on September 12, three hours after the Soyuz spacecraft launched by Baikonur Cosmodrome in Kazakhstan. The station crew number would have been nine if Boeing’s Starliner was safe to bring Sunita Williams and Barry Wilmore back to Earth.

They launched to the ISS on June 5 for Boeing’s 8-day Crew Flight Test mission. But the spacecraft malfunctioned and returned empty on September 7. The duo will now stay in space until SpaceX rescues them in February 2025.

The other astronauts are Ye Guangfu, Li Cong, Li Guangsu from China living and working aboard the Tiangong Space Station. They launched to space as the Shenzhou-18 crew on April 24 this year.

And the third crew consists of the Polaris Dawn astronauts launched by SpaceX on September 10. Four members of it reached the highest-Earth orbit for the first time since December 1972 and are set to perform the first-ever spacewalk in a commercial mission today. More about it here. This number will remain intact until the Polaris crew returns on September 14.

NASA Postpones October 10 Launch Of Europa Clipper Mission Due To Hurricane Milton

Published

By


NASA is foregoing the opportunity to launch its Europa Clipper mission this week. It was supposed to launch on October 10 on SpaceX’s Falcon Heavy rocket but bad weather has caused a change of plans.

The agency cited hurricane conditions that are building up near the launch site at the Cape Canaveral Space Force Station in Florida.

Expecting high winds and heavy rain, the mission team has secured the Europa Clipper in a SpaceX facility at the Kennedy Space Center nearby. According to the National Hurricane Center (NHC), the Hurricane in the Gulf of Mexico will intensify by midweek when it hits Florida’s east coast. The launch site is on the west coast.

“While it is too soon to specify the exact magnitude and location of the greatest impacts, there is an increasing risk of life-threatening storm surge and damaging winds for portions of the west coast of the Florida Peninsula beginning early Wednesday,” the NHC stated.

“The safety of launch team personnel is our highest priority, and all precautions will be taken to protect the Europa Clipper spacecraft,” Tim Dunn, senior launch director at NASA’s Launch Services Program, said in a statement.

The new launch date for the mission is yet to be announced but NASA says that opportunities are available until November 6.

“Once we have the ‘all-clear’ followed by facility assessment and any recovery actions, we will determine the next launch opportunity for this NASA flagship mission,” Dunn said.

Europa Clipper is the largest spacecraft NASA has ever made for an exploration mission. Equipped with nine instruments, the probe will measure more than 100 feet when it fully unfurls its solar panels.

The mission has an objective to investigate Jupiter’s moon Europa, which scientists believe has a vast ocean of liquid water beneath its icy crust. Using its instruments, Clipper will study Europa’s composition and geology, its icy surface and the chemistry of the suspected ocean to determine if there are conditions that could support life.

Blue Origin Set To Launch Brand New Human Rated Capsule To Space Today; Watch Live

Published

By



Blue Origin is introducing its brand new space capsule today. The New Shepard spacecraft, which was originally scheduled to launch on the NS-27 mission at 6:30 pm IST from West Texas, will now lift off at 9:40 pm. This is the second human-rated vehicle which is being tested to expand the company’s flight capacity in order to “meet growing customer demand.”

You can watch the launch live on BlueOrigin.com. The webcast will begin 15 minutes before liftoff.

The new capsule named RSS Kármán Line, the company said, is equipped with advanced technologies that will improve its performance, reusability and accommodations for payloads on the booster.

Similar to its predecessor, 99 percent of the RSS Kármán Line’s components including the booster, capsule, engine, landing gear, and parachutes are reusable.

The vehicle will be tested by flying it to the Kármán Line, the internationally recognised boundary of space 100 km above Earth. This is an uncrewed flight meaning there are no humans onboard. Instead, the capsule will be carrying 12 payloads – five on the booster and seven inside the crew capsule.

The payloads include new navigation systems developed for New Shepard and Blue Origin’s upcoming rocket New Glenn; two different LIDAR sensors for the Lunar Permanence program – a collaboration between NASA and Blue Origin and ultra-wideband proximity operations sensors flying as part of a NASA TechFlights grant with Blue Origin’s Space Systems Development group.

Nobel Prize 2024 In Medicine Awarded To Two US Scientists For Discovery Of MicroRNA

Published

on

By



Scientists Victor Ambros and Gary Ruvkun have been jointly awarded the 2024 Nobel Prize in Medicine for “the discovery of microRNA and its role in post-transcriptional gene regulation.”

RNA or Ribonucleic Acid plays a key role in cell function. There is a messenger RNA or mRNA that directs the cells to make proteins using natural machinery.

The microRNA is a new class of tiny RNA molecules that play a crucial role in gene regulation. Gene regulation is basically the process by which cells control the expression of genes. It helps them decide which genes to turn on or off, and to what extent. This allows the cells to adapt to different environment, develop and grow and maintain cellular balance among other key functions.

Failure in gene regulation can cause mutations which can cause diseases and unregulated cell growth that can lead to cancer and even diabetes. Cells and tissues have been found to develop abnormally without microRNAs.

“Their groundbreaking discovery revealed a completely new principle of gene regulation that turned out to be essential for multicellular organisms, including humans,” a release from the Nobel committee said.

The finding also revealed an entirely new dimension to gene regulation and that microRNAs are proving to be fundamentally important for how organisms develop and function.

The discovery of the microRNA by Ambros and Ravkun was made in 1993 after years of research that started in the 1980s on a 1mm long roundworm. Thanks to their findings, scientists now know that gene regulation by microRNA has enabled the evolution of increasingly complex organisms and its abnormal regulation can cause many diseases. Besides, mutations in genes coding for microRNAs have caused congenital hearing loss, eye and skeletal disorders in humans.

More about the Nobel Prize winners

Victor Ambros is Silverman Professor of Natural Science at the University of Massachusetts Medical School after serving as a Professor at Dartmouth Medical School from 1992-2007. After receiving his PhD from Massachusetts Institute of Technology (MIT), Cambridge in 1979, he also did postdoctoral research from 1979-1985 at the institution. He later became a Principal Investigator at Harvard University, Cambridge.

Gary Ruvkun is a Professor of Genetics at the Harvard Medical School. He has also worked as a Principal Investigator at Massachusetts General Hospital. Ruvkun received his PhD from Harvard University in 1982 and worked as a postdoctoral fellow at Massachusetts Institute of Technology (MIT), Cambridge from 1982-1985.

The two scientists will share the award and approximately $1 million that comes with the diploma.
