Keeping track of spacecraft as Earth's water alters its spin
Write a comment
External gravitational forces, predominantly from the Sun and Moon, are constantly and predictably acting on our planet. While the Sun's enormous gravity keeps Earth in orbit, the gentle tug of the Moon has, over billions of years, quite dramatically slowed its spin, increasing the length of a day on Earth.

The ISRO has been keen on roping in the domestic private sector to finance the rocket manufacturing and satellite launch business so that it can itself focus on research and the heavy satellite launch market. Hoping to get a share of the global satellite launch business, India allocated a $1.4 billion fund for NewSpace India Ltd.

Russia's Fregat upper stage has placed all the 38 satellites in target orbits after the launch of the Soyuz-2.1a carrier rocket, Dmitry Rogozin, the head of the Russian State Space Corporation Roscosmos, said on Monday.
"Separation of 33 satellites has taken place," Rogozin said, adding that five satellites were placed in orbit earlier.

The United States is leading the way to a new era of commercial space transportation with a final rule that streamlines the licensing process for private sector launch and reentry operations.

NASA's plan to fly a helicopter on Mars for the first time in a few weeks could start a new era of interplanetary exploration like the space agency's little Sojourner rover did in the 1990s, according to several experts.
The Mars helicopter, Ingenuity, will be dropped from the Perseverance rover soon, but NASA hasn't determined the exact date. The rover ejected a shield that covered the Kepler Communications reports successful Launch of two GEN1 satellites

Kepler Communications welcomed two new satellites into their constellation today, further expanding the active constellation to 15 satellites in total. These two satellites, KEPLER-6 and KEPLER-7, were successfully launched via Soyuz 2 out of Baikonur Cosmodrome as part of the CAS500-1 mission at approximately 02:07 AM EDT.

Russia on Monday put 38 foreign satellites into orbit after a succesful launch from the Baikonur cosmodrome in Kazakhstan following delays due to technical issues.
Video published by the Russian space agency Roscosmos showed its Soyuz rocket launching against grey and cloudy skies at 0607 GMT.
"The Soyuz-2.1a carrier rocket with the Fregat upper stage and 38 spacecraft from 18 countries took off from the Baikonur cosmodrome," Roscosmos said on its Twitter account.
Later Monday, Roscosmos said in a statement that the rocket had successfully placed into orbit the 38 satellites from more than a dozen countries, including South Korea, Japan, Canada, Saudi Arabia, Germany, Italy and Brazil.
Among them was the Challenge-1, the first satellite made completely in Tunisia, which was created by the Telnet telecommunications group.
The launch was twice postponed from Saturday after a surge in voltage was detected.
Tunisia engineers reach for stars with satellite launch

Tunisia celebrated the launch Monday of its first domestically made satellite, hoping it would inspire young engineers to reach for the stars at home rather than join those emigrating overseas.
Challenge-1, built by a team from telecommunications giant TelNet, blasted off along with 37 other satellites aboard a Russian Soyuz rocket from the Baikonur cosmodrome in Kazakhstan on Monday.
That made Tunisia the sixth African country to manufacture its own satellite and see it reach space.
"It's a source of pride to have taken part in this project," said Khalil Chiha, 27, who trained at Tunisia's National Engineering School in the central city of Sfax.
"Working in the aeronautical or aerospace sector is a dream."
Tunisia had been struck by an economic crisis and skyrocketing unemployment even before the coronavirus pandemic, and recent months have seen growing anti-government protests.
Keeping track of spacecraft as Earth’s water alters its spin

- Mass is constantly being redistributed around our planet, as Earth’s atmosphere, oceans and other bodies of water on and under the surface melt, shift and stir.
- This mass redistribution alters Earth’s centre of gravity, which in turn speeds up and slows down the planet's spin – and so the length of the day – as well as changing the orientation of its 'spin axis'.
- These changes to Earth’s spin and orientation occur over relatively short timescales of days and weeks, and threaten communication between ground stations and missions in orbit and across the Solar System.
