PSLV-C7 was a mission of the Indian Polar Satellite Launch Vehicle (PSLV) rocket, launched on January 10, 2007, by the Indian Space Research Organisation (ISRO) from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh.

Contents

The mission consisted of Space Capsule Recovery Experiment, ISRO's first reentry mission, [1] along with Cartosat-2, an Earth observation satellite, LAPAN-TUBsat, Indonesia's first remote sensing satelite, and Pehuensat-1, an Argentine educational satellite. [2]

The mission was an important mission is the history of PSLV, because it had many new additions to the rocket. The mission also had the first use of Dual Launch Adapter, (DLA). [3]

Space Capsule RecoveryExperiment

The Space Capsule Recovery Experiment (SCRE or more commonly SRE or SRE-1) is an Indian experimental spacecraft. It's the first step in their Gaganyaan program of ISRO which aim to send humans to space. It orbited the Earth for 12 days before re-entering the Earth's atmosphere and splashing down into the Bay of Bengal at 04:16 UTC on January 22. [5] It also did Research on reusable Thermal Protection System, navigation, guidance and control, hypersonic aero-thermodynamics, management of communication blackout, deceleration and flotation system and tested recovery operations. [6]

Cartosat-2

Cartosat-2 is an Earth observation satellite in a Sun-synchronous orbit and the second of the Cartosat series of satellites. It consists of a panchromatic (PAN) camera that take black and white pictures of the Earth in the visible region of the electromagnetic spectrum. It can produce images 1 metre in resolution. [7]

LAPAN-TUBsat and Pehuensat-1

Pehuensat-1 is an Argentinian amateur Radio satellite created by students of Universidad Nacional del Comahue. [8] LAPAN-TUBsat is an Indonesian micro satellite, weighing 56 Kilograms, orbiting at 630 kilometers above Indonesia. This satellite travels through polar orbit across the archipelago two or three times each day.

Dual Launch Adapter

Dual Launch Adapter can be used to integrate 2 or more satellites on a single Launch. Note: This shows the DLA from the later PSLV-C40 mission PSLV-C40- Render of payload fairing with Dual Launch Adapter.jpg

It's an adapter designed to carry medium class (~1000 kg) payloads in PSLV. It consists of a Carbon Fibre composite, arranged in Honeycomb sandwich shells. With an aluminum core. It consists of three structures, DLA-U (upper), DLA-M (middle), and DLA-L (lower). DLA is mounted of the fourth stage of PS4, by bolting the DLA-L with Payload Adapter (PLA). DLA-U carries Cartosat-2, and SRE is connected to PLA via a band clamp separation system. DLA includes cutouts in which electrical connectors, sensors, cooling system of the satellite etc. can be mounted.

Team of ISRO scientists who were part of the mission were awarded the prestigious team achievement award of the International Academy of Astronautics. The award was given to them at Glasgow, on September 28.

ISRO Chairman Madhavan Nair told the press "We've done it perfectly", after the launch. [9] Dr V Jayaraman, director, earth observation system, said "We believe we can offer our products at one-fifth of the cost of our competitors, The size of the international market (for such images) is about $300 million-$500 million."

The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
