Adelaide, Sep 29: Elon Musk, founder of SpaceX on Friday unveiled its plans to put humans on Mars as early as 2024.

Speaking on the final day of the 68th International Astronautical Congress (IAC) here, SpaceX CEO Elon Musk made the announcement of the plans, reports Xinhua news agency.

Musk, who also serves as the CEO of automotive company Tesla, said SpaceX was aiming for cargo missions to the Red Planet in 2022 and crew with cargo by 2024.

He said that missions to Mars would be launched every two years from 2022 onwards with colonisation and terraforming to begin as soon as the first humans arrive in order to make it “a really nice place to be”.

“It’s about believing in the future, and thinking that the future will be better than the past,” Musk said.

SpaceX also announced its new BFR rocket on Friday.

“I can’t emphasise enough how profound this is, and how important this is,” Musk told the Congress as the keynote speaker on the final day.

The new BFR has the highest capacity payload of any rocket ever built, meaning it has the lowest launch cost, due to its status as a fully reusable rocket while also being the most powerful.

“It’s really crazy that we build these sophisticated rockets and then crash them every time we fire,” Musk said.

He said that the new BFR could carry a 40-carriage spaceship to Mars with two or three people occupying each carriage.

The rocket is capable of flying from Earth to the Moon and back without refuelling, making creating a base on the Moon, dubbed Moon Base Alpha, achievable in near future.

SpaceX intends for the new, scaled-down BFR to replace its other flagship rockets, the Dragon, Falcon 9 and Falcon Heavy.

Musk said the BFR could even be used for international flights on Earth, promising to cut most long-distance Earth flights to just half an hour.

He said the rocket could travel from New York City to Shanghai in 37 minutes at a maximum speed of 18,000 miles (28,968 km) per hour.

Funding for BFR development will come from SpaceX’s satellite and International Space Station (ISS) revenue.

SpaceX’s announcement came hours after Lockheed Martin revealed new technology that would see it land on Mars in partnership with NASA by 2030.

SpaceX estimated this year that a permanent, self-sustaining colony on Mars was 50 to 100 years away.(IANS)

SpaceX to Launch Twin NASA Water Cycle Tracker Satellites

The satellites are scheduled to launch at 3.47 p.m. EDT from Vandenberg Air Force Base in Central California

On its way to deploy five Iridium Next communications satellites on Tuesday, a SpaceX Falcon 9 rocket will also launch twin NASA satellites that will monitor Earth’s water cycle, marking a unique rideshare arrangement.

The satellites are scheduled to launch at 3.47 p.m. EDT from Vandenberg Air Force Base in Central California. (This corresponds to 1.17 a.m. Wednesday India time), NASA said.

The two Gravity Recovery and Climate Experiment Follow-On mission (GRACE-FO) spacecraft will follow each other in orbit around Earth, separated by about 220 km.

On liftoff, the Falcon 9 first-stage engines will burn for approximately two minutes and 45 seconds before shutting down at main engine cutoff (MECO).

The Falcon 9’s first and second stages will separate seconds later. Then, the second-stage engine will ignite for the first time (SES1) and burn until the vehicle reaches the altitude of the injection orbit, 490 km.

While this burn is going on, the payload fairing — the launch vehicle’s nose cone — will separate into two halves like a clamshell and fall away.

When the rocket’s second stage has completed its ascent to the injection orbit altitude, it will pitch down (its nose points down) 30 degrees and roll so that one of the twin GRACE-FO satellites is facing down, toward Earth, and the other is facing up, toward space.

Then the second stage engine will cut off (SECO).

About 10 minutes after liftoff, a separation system on the second stage will deploy the GRACE-FO satellites.

Separation will occur over the Pacific Ocean at about 17.5 degrees North latitude, 122.6 degrees West longitude.

The first opportunity to receive data from the spacecraft will occur at NASA’s tracking station at McMurdo, Antarctica, about 23 minutes after separation, NASA said.

After the GRACE-FO satellites are deployed, the Falcon 9 second stage will coast for half an orbit before reigniting its engine (SES2) to take the Iridium Next satellites to a higher orbit for deployment.

GRACE-FO, a collaborative mission of NASA and the German Research Centre for Geosciences (GFZ), continues the work of the original GRACE mission in observing the movement of water and other mass around our planet by tracking the changing pull of gravity very precisely. (IANS)
