Sriharikota: The Indian Space Research Organisation (ISRO) on Monday put into orbit the Emisat, an electronic intelligence satellite for the Defence Research and Development Organisation (DRDO) in a copy book style.

The notable aspects of this space mission were the flying of a new variant of the Polar Satellite Launch Vehicle (PSLV); switching off and on the fourth stage engine couple of times; and the use of the fourth stage as an orbital platform carrying three experimental payloads.

At 9.27 a.m., the PSLV rocket standing at 44.5 metres tall and weighing about 239 tonne with a one-way ticket, hurtled itself towards the skies ferrying the Emisat and 28 international customer satellites — 24 from the US, two from Lithuania and one each from Spain and Switzerland.

With the fierce orange flame at its tail lighting, the rocket slowly gathered speed and went up enthralling the people at the rocket port while the rocket’s engine noise like a rolling thunder adding to the thrill.

“It is a special mission for us. We will be using a PSLV rocket with four strap-on motors. Further, for the first time we will be trying to orbit the rocket at three different altitudes,” ISRO Chairman K. Sivan had earlier told media persons.

The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel.

In its normal configuration, the rocket will have six strap-on motors hugging it’s first stage.

On January 24, the ISRO flew a PSLV with two strap-on motors while in March, it had four strap-on motors.

The space agency also has two more PSLV variants — Core Alone (without any strap-on motors) and the larger PSLV-XL.

The ISRO selects the kind of rocket to be used based on the weight of satellites it carries.

 

India again creates history by putting defence satellite Emisat into orbit with electronic intelligence:

 

Even though ISRO has done this earlier, it was more thrilling to note the rocket’s fourth stage/engine was cut/switched off.

More thrilling aspect came in when rocket’s fourth stage/engine was cut/switched off in just over 16 minutes after the lift off.

Forty seven seconds later, the Emisat was ejected at an altitude of about 753 km.

“There is increased demand for satellites from strategic sectors. About six/seven satellites are planned to be built,” a senior official told media persons on the condition of anonymity.

India will also be launching two more defence satellites sometime in July or August with its new rocket Small Satellite Launch Vehicle (SSLV).

Meanwhile, at about 60 minutes after the PSLV’s lift-off, its fourth stage will be restarted and run for about 10 seconds before it will be cut off again.

At about 108 minutes after the lift off, the rocket’s fourth stage will again restarted for few seconds before it will be again cut off.

Finally, at about 110 minutes after the rocket left the earth, the first of the 28 foreign satellites will be ejected and in five minutes all other satellites will be ejected.

Again the fourth stage will be restarted and stopped twice to bring its altitude to 507 km at the end of three hours after the lift off.

At this point the fourth stage will turn into an orbital platform for three experimental payloads: (a) Automatic Identification System (AIS) from ISRO for Maritime satellite applications capturing messages transmitted from ships (b) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to assist amateur radio operators in tracking and monitoring position data and (c) Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) – for the structural and compositional studies of ionosphere, the space agency said.

Trump knew exactly what was going on: Giuliani aide

Published

By

Washington: An aide to Rudy Giuliani, Donald Trump’s personal lawyer, has said that the US President “knew exactly what was going on” regarding efforts to pressure Ukraine into investigating Democratic presidential candidate Joe Biden and his son, it was reported on Thursday.

Ukrainian-American businessman Lev Parnass, who is facing separate criminal charges, made the comments in an interview with MSNBC on Wednesday after letters, phone records, notes and flash drives were obtained from him earlier this week, the BBC said in a report.

Documents show that the Ukraine-born Parnas was in regular contact with Giuliani as well as Ukrainian officials, and suggests that the businessman was directly involved in trying to have Ukraine’s President Volodymyr Zelensky look into the Bidens.

In the interview, Parnas said Trump was “aware of all my movements”.

“I wouldn’t do anything without the consent of Rudy Giuliani or the President. Why would President Zelensky’s inner circle or (Interior) Minister (Arsen) Avakov or all these people or (former) President (Petro) Poroshenko meet with me?

“Who am I? They were told to meet with me. And that’s the secret that they’re trying to keep. I was on the ground doing their work,” he added.

Parnas further said that the President was lying and knew that unless there was an investigation into Joe Biden and his son Hunter, who was a director of a Ukrainian gas company, military aid to Kiev would be withheld.

He also claimed that the investigation was about digging up dirt on Joe Biden.

Meanwhile, some of the materials obtained show Parnas and Giuliani discussing the removal of Marie Yovanovitch, the then US ambassador to Ukraine, said the BBC report.

In Wednesday’s interview, Parnas claimed the only motivation to get Yovanovitch removed from her post was because she was in the way of the effort to get Ukraine to announce an investigation into Joe Biden.

Trump was impeached by the Democrat-controlled US House of Representatives on December 18, 2019 and is accused of abuse of power and obstruction of Congress.

The two articles of impeachment were sent to the Republican-majority Senate on Wednesday night, paving the way for the starting of a trial against the President.
