On September 11, 2024, Earth reached a new milestone in space travel, with a record 19 people currently orbiting our planet. This new record was set when a Russian Soyuz rocket launched three new astronauts towards the International Space Station (ISS). The previous record of 17 was set last year. This significant increase in human presence in space highlights the growing activity and collaboration in the realm of space exploration.

Soyuz Launches New Crew

The Soyuz mission took off on September 11, 2024, carrying NASA astronaut Don Pettit and Russian cosmonauts Alexey Ovchinin and Ivan Vagner. Their arrival at the ISS is expected to take place around 3:30 p.m. EDT (1930 GMT) on the same day.

This trio joins the existing nine astronauts aboard the ISS, including NASA’s Michael Barratt, Tracy Caldwell-Dyson, Matthew Dominick, Jeanette Epps, Barry Wilmore, and Suni Williams, along with cosmonauts Nikolai Chub, Alexander Grebenkin, and Oleg Kononenko.

International and Private Space Missions

Currently, three astronauts are residing on China’s Tiangong space station: Li Cong, Li Guangsu, and Ye Guangfu. Additionally, four astronauts are on the Polaris Dawn mission aboard a Crew Dragon capsule. This mission, which began on September 10, 2024, aims to set new records in private space exploration, including a planned spacewalk by Jared Isaacman and Sarah Gillis on September 12, 2024.

Records and Milestones

The record for the most people in space at one time was 20, set briefly in May 2023 and then again on January 26, 2024. This record was achieved when six space tourists joined 14 astronauts in orbit. For those who consider the Kármán line as the boundary of space, the record for most people in space remains at 19, tied by the Soyuz launch and Blue Origin’s suborbital New Shepard mission on December 11, 2021.

This achievement reflects the growing pace of human space exploration and international cooperation in orbit.

Is the Universe Slowing Down? Astronomers Detect Signs of Fading Dark Energy

Published

By

Astronomers from Yonsei University and DESI data analyses indicate dark energy, long believed constant, may be weakening. Corrected supernova results hint that cosmic acceleration is slowing—a possible “cosmic slowdown.” If true, this could help resolve the Hubble tension and redefine how the universe’s expansion and ultimate fate are understood.

Scientists Create Bullet-Proof Fiber Stronger and Thinner Than Kevlar

Published

By

Researchers have created a new fiber that surpasses Kevlar in bullet-stopping power while being much thinner. Made by aligning advanced aramid chains with carbon nanotubes, the material absorbs over twice as much energy as previous record-holding fibers. The breakthrough could lead to lighter, stronger armor for military, law enforcement and personal safety uses.
