M'sian satellite in orbit

CAPE CANAVERAL (Florida) - A PIONEERING rocket company that wants to take over the job of sending US astronauts to the International Space Station launched an imaging satellite into orbit late on Monday for a Malaysian firm, its first paying customer.

Space Exploration Technologies' Falcon 1 rocket lifted off from Omelek Island in the Kwajalein Atoll in the Western Pacific at 11.35pm EDT (11.35am Singapore time) on Tuesday carrying the 400-pound (180kg) RazakSAT satellite, designed and built by ATSB of Malaysia.

The spacecraft has black-and-white and colour cameras to take high-resolution pictures of agricultural lands, forests, urban centres and other targets in Malaysia for commercial and government customers.

It was the fifth flight for Space Exploration Technologies, a privately funded California firm founded by Internet entrepreneur Elon Musk, a co-creator of the PayPal financial services company that was purchased by eBay for US$1.5 billion (S$2.19 billion) in 2002.

SpaceX's first three launches in 2006, 2007 and 2008, fell short of reaching orbit.

Its fourth launch last September successfully put a dummy payload into orbit.

In addition to its Falcon 1 rocket, which can put a half-ton payload into orbit for about US$8 million, SpaceX is developing a heavy-lift Falcon 9 rocket that can carry 11 tonnes to low-Earth orbit, or four tonnes to an orbit 22,300 miles above the planet, for about US$40 million.

'We're the lowest prices on the market for comparable capabilities,' Mr Musk said in a recent interview.

The firm's biggest customer is Nasa, which has reservations for more than half of SpaceX's two dozen upcoming missions. The company has contracts to develop and deliver a space station cargo vehicle. It also is petitioning for a US$300 million contract addition to upgrade its Dragon capsule to ferry astronauts to and from the space station after Nasa retires its space shuttle fleet next year. -- REUTERS


Any implication?

I think you can probably get better resolution pics using google maps (1m and under compared to 2.5/5m for razaksat).

It can however provide a pic 14 times a day or every ~100min so its semi-real time.

at 9 degrees inclination.. i think they are more interested in south china sea, southern thailand and southern phillipine then singapore.

There's not much they can see if they look this way anyway. Most of our military equipment is always under overhead cover.

It can be use to spot for any mass mobilisation of our equipments during a crisis, giving them time to react to any impending invasion. I wonder if it is equipped with SAR?

do you mean whether it is carrying a SARSAT (Search And Rescue Satellite) payload?

I was actually referring to a synthetic aperture radar in reference to the black and white camera.

Well, everyone's looking at everyone's equipment movement now...

Its a camera not a radar. This means video imaging (2D flat) but not sonar-type imaging. No real indication of frame capture rate but it is multi-spectral ie different spectrums. There's probably ground computer algorithms to aid 3D reading.

I disagree. Visibility is normally within 15 degrees latitude of inclination. As SG is at 1 deg latitude. My understanding is that SG should definitely within visual range. Also when orbital inclination is higher than latitude, there would be an intersection at some point in time.

Interesting to read about CRISP as well and the sat data they have access to.

Then one looks at the defence applications that sats like SPOT 5 does...
