09:48 UTC Liftoff the Delta 2 with NPP – the world’s next-generation weather watcher heads to space
10:47 UTC NPP spacecraft has been released from the Delta 2 rocket’s second stage

11:26 UTC Confirmed deployment of P-POD-1 with AubieSat-1, Explorer-1 Prime and M-Cubed/COVE
11:28 UTC Confirmed deployment of P-POD-2 with RAX-2
11:30 UTC Confirmed deployment of P-POD-3. This P-POD contains the two-satellite DICE CubeSats (downlink at 465 MHz)




AubieSat 1 was made by Auburn University undergraduate students to study radio wave propagation through the ionosphere and test
protective films for solar panels.
Explorer 1 (Prime) Unit 2 from Montana State University also plans to probe space weather by monitoring trapped electrons in the horns of the radiation belts. It is named for America’s first satellite in space.
M-Cubed — the Michigan Multipurpose Minisat — comes from the University of Michigan to image the Earth and demonstrate the craft’s design for use by future projects.
The Radio Aurora Explorer 2, also from the University of Michigan, will study the microphysics that lead to plasma conditions that disrupt satellite communications.
The DICE (Dynamic Ionosphere CubeSat Experiment) will obtain electric field and electron density measurements for space weather research. The mission partners include Utah State, Clemson, Embry-Riddle Aeronautical University and the Atmospheric and Space Technology Research Associates.

PW-Sat to launch in January

PW-Sat, a 1U CubeSat to be launched on the first VEGA flight in January, will carry a 145 to 435 MHz Amateur Radio transponder.

The single channel transponder will operate in a similar way to AO-16. The uplink on 145.900 MHz will be FM and the downlink on 435.020 MHz will use the BPSK telemetry beacon transmitter to produce Double Sideband (DSB) that can be received on an SSB radio.

PW-Sat should be launched into a 1450 by 300km 69.5 degree orbit and may be expected to have a lifetime of about 2 years before re-entry. It was built by students of Warsaw University of Technology in cooperation with the Space Research Centre and will be Poland’s first satellite.

PW-Sat has five modes of operation:
1. Receive only mode – no downlink
2. Beacon CW mode – Downlink On-Off Keying (OOK) CW (1kHz) 12 WPM on 435.020 MHz
3. Beacon BPSK mode – Downlink BPSK (3 kHz) 1200 bps AX25 (1 frame on 20 sec) on 435.020 MHz
4. Control communication mode. Downlink BPSK (3 kHz) 1200 bps AX25 on 435.020 MHz
5. Voice Repeater mode (aka “AO16″ mode) – Uplink145.900MHz FM (15 kHz) Downlink 435.020MHz DSB (3 kHz)

One Soyuz launcher, two Galileo satellites.

The first pair of satellites for Europe's Galileo global navigation satellite system has been lofted into orbit by the first Russian Soyuz vehicle ever launched from Europe's Spaceport in French Guiana in a milestone mission.

The Soyuz VS01 flight, operated by Arianespace, started with liftoff from the new launch complex in French Guiana at 10:30 GMT (12:30 CEST) on 21 October.
All of the Soyuz stages performed perfectly and the Fregat-MT upper stage released the Galileo satellites into their target orbit at 23 222 km altitude, 3 hours 49 minutes after liftoff.

Thanks to the KN-SAT1 team .

We are very thankful for the continuous support from you, by sending us the
beacon data. We are right now trying to estimate the performance of the
satellite and will be planning to perform the operation of the payload in
the next couple of days. Before the operation of the payload is begun, we
would like to do a small performance test with respect to the RF link. We,
therefore request you to kindly keep sending the beacon signal and also try
to send the details of the RF signal performance over the entire length of
the pass.


I would like to quote some of the words from the SRMSAT project Students and
Mentors

"IT IS A GREAT MORAL BOOSTING CONTINUING INFO FLOW FROM YOU FOR THE SRMSAT

SRM University's satellite to take to the skies

Students of SRM University explaining the features of SRMSAT to be launched along with Megha-Tropiques satellite, on board PSLV-C18, to university president P. Sathyanarayanan and Chancellor T.R. Pachamuthu in Chennai on Monday. Photo: M. Vedhan

As the PSLV-C18 carrying Megha-Tropiques, an Indo-French venture to study the atmosphere in the tropical regions, blasts off from Satish Dhawan Space Centre at Sriharikota on October 12, students will be holding their breath at the ground station at SRM University in the city outskirts.

Along with Megha-Tropiques, SRMSAT, a nano-satellite, to monitor the green house gases, carbon-dioxide and water vapour in the tropics using a grating spectrometer will be launched.

“Fifty students were involved in design and development of SRMSAT, one of the first nano-satellites to be launched by a private university in the country,” said P. Sathyanarayanan, president, SRM University.

“There is a dedicated lab at the university. All the students involved in the project worked at the lab, after college hours, for the past two years, choosing to stay late in the night designing and testing each and every instrument,” says L.B. Vishal, a mechanical engineering student.

When they found that the power amplifier on board was dissipating heat, the students came up with heat sinks. Likewise, communication systems were arrived at after a lot of simulation. Students of 12 departments began work on the satellite with the survey of literature and Loganathan, a former ISRO scientist and product architect of space systems at the university, was available 24x7 to make the dream project a reality. ISRO scientists conducted a review of the project every month and gave insights.

Of cuboid model, the nano-satellite weighs 10.4 kg with three solar panels and was made at a cost of Rs.1.5 crore. The grating spectrometer will monitor earth-based sources and sinks of green house gases for the next two years.

Already in place, the ground station consists of two Yagi-Uda antennae with low noise amplifiers and Trans-receiver and auto tracking is through a satellite tracking programme. “The ground station has been tested by tracking the existing satellites,” says D. Narayana Rao, Director, Research.

“The University is in talks with ISRO to start a Centre for Space Sciences in its Chennai campus. It will take six months to crystallize,” Mr. Sathyanarayanan said. University Chancellor T.R. Pachamuthu and Vice-Chancellor M. Ponnavaikko were present.

ROSAT - 1 in 2000 chance of injury !!

NASA calculates a 1-in-3200 chance of UARS causing injury or damage. But at the end of October or beginning of November, ROSAT – a 2.4-tonne X-ray telescope built by the German aerospace lab DLR and launched by NASA in 1990 – will re-enter the atmosphere, presenting a 1 in 2000 chance of injury.

The higher risk stems from the requirements of imaging X-rays in space, says DLR spokesperson Andreas Schütz. The spacecraft's mirrors had to be heavily shielded from heat that could have wrecked its X-ray sensing operations during its eight-year working life. But this means those mirrors will be far more likely to survive a fiery re-entry.

At the European Space Agency in Darmstadt, Germany, the head of the space debris office, Heiner Klinkrad, agrees that ROSAT's design means more of it will hit the surface. "This is indeed because ROSAT has a large mirror structure that survives high re-entry temperatures," he says

US Strategic Command tracks all space objects and the US-government-run Aerospace Corporation lists both upcoming and recent re-entries on its website. But ROSAT is not yet on the upcoming list because its re-entry time is far from certain.

The moment a craft will re-enter is difficult to predict because it is determined by two main factors.
First, the geometry of the tumbling satellite as it enters the upper atmosphere, which acts as a brake.
Second, the behaviour of the upper atmosphere itself, which grows and shrinks with the amount of solar activity, says Hugh Lewis, a space debris specialist at the University of Southampton, UK.

"Solar activity causes the atmosphere to expand upwards, causing more braking on space objects. The reason UARS is coming back sooner than expected is a sudden increase in solar activity. Indeed, we expect to see a higher rate of re-entries as we approach the solar maximum in 2013," he says.

Geomagnetic Disturbance Index

North West Research Associates.Space weather services

The Ap index is a measure of the general level of geomagnetic activity over the globe for a given (UT) day. It is derived from measurements made at a number of stations world-wide of the variation of the geomagnetic field due to currents flowing in the earth's ionosphere and, to a lesser extent, in the earth's magnetosphere. The official values for Ap (and other related indices of geomagnetic activity such as the three-hour Kp index) are calculated by the GeoForschungsZentrum Potsdam Adolf-Schmidt-Observatory for Geomagnetism, D-14823 Niemegk (Germany),

FUNcube Dongle as a Radio Telescope?

A Radio Astronomy paper describes the use of the AMSAT-UK FUNcube Dongle Software Defined Radio as part of a Radio Telescope.

In the paper Dr David Morgan of the British Astronomical Association Radio Astronomy Group (BAA-RAG) describes how he used the FUNcube Dongle as the heart of a Radio Telescope operating on 1420 MHz.

He concludes that “A newly available SDR component has been shown to be very capable of acting as the heart of a simple and inexpensive three component radio telescope.”.

My prediction for ROSAT re-entry

My prediction for ROSAT re-entry.
With in 20 days +-13 days !! :(

DLR information for ROSAT re-entry
The time and location of re-entry cannot be predicted precisely At present, scientists expect the X-ray satellite, which completes an orbit around Earth in about 90 minutes, to re-enter around the end of October 2011. Currently, this date can only be calculated to within plus/minus five weeks.This time slot of uncertainty will be reduced as the date of re-entry approaches. However, even one day before re-entry, the estimate will only be accurate to within plus/minus five hours .All areas under the orbit of ROSAT, which extends to 53 degrees northern and southern latitude could well be affected by its re-entry.

Happy 54th birthday to Sputnik I and the space race

by Lauren Gold
Oct 04, 2011


The Soviet Union launched Sputnik I into Earth orbit 54 years ago today, winning the first lap of the space race to the shock of the United States.

“Without a doubt, Sputnik I was a huge milestone in the history of the space race. It marked the first time that humans successfully flew something higher than the boundaries of the earth’s atmosphere,” said Michael Smutko, distinguished senior lecturer of physics and astronomy at Northwestern University.

The 184-pound, shiny, spherical satellite could be seen with the naked eye, and ham radio operators picked up its beep. Suddenly, the Soviet Union had surpassed the U.S. in science. In the midst of the Cold War, the Soviets had the technology to place spacecraft in orbit over the U.S. It was an advantage no one had had until that point.
