<p>Indian Space Research Organisation (ISRO) is gearing up to carry out the&nbsp;fourth Earth-bound manoeuvre in its Aditya-L1 mission. The manoeuvre will take place at 2 am IST on September 15 (2330 GMT on September 14). It is a crucial step as the Indian space agency is seeking to place the spacecraft in halo orbit around the Lagrange Point 1 (L1) of the Sun-Earth system.</p>

<p>The scheduled manoeuvre is part of a series of orbit-raising manoeuvres which will prepare the spacecraft for its journey further to the L1 point.</p>

<p>India's first space-based solar observatory was launched on September 2. Since then, three Earth-bound manoeuvres have been successfully carried out. The most recent took place on September 10. At the end of the third manoeuvre, the Aditya L1 spacecraft attained an orbit of 296 km x 71676 km, as per data released by ISRO.</p>

<p>The fourth manoeuvre will further raise the spacecraft's orbit.</p>

<p>The L1 point was discovered by mathematician Joseph Louis Lagrange. It is considered to be the most significant of the Lagrangian points for observation of the Sun. A spacecraft that's placed in a halo orbit around the L1 point would be in a position to observe the Sun continuously without any eclipses or occultation. This will help to observe solar activities in real-time.</p>

<p>Aditya-L1 is carrying seven payloads. These are designed for various layers of the Sun. Out of seven, four will directly view the Sun. The other three payloads will perform in-situ studies of particles and fields at the L1 point.</p>

<p>The instruments on Aditya-L1 are expected to provide important information about coronal mass ejection, coronal heating, pre-flare and flare activities among other solar phenomena of importance.</p>

<p>India is fresh off the success of the Chandrayaan-3 mission. With a successful landing near the Moon's south pole, India has become the first country to land a spacecraft in this region. The rover and the lander are currently in sleep mode with chances of waking up again on Sep 22.</p>

Aditya-L1 mission: ISRO gears up to carry out fourth manoeuvre on Sept 15

<p>Beijing on Wednesday&nbsp;blamed US "provocation" for an incident involving a Chinese plane&nbsp;aggressively manoeuvring&nbsp;near an American surveillance aircraft over the South China Sea.</p>

<p>"The United States' long-term and frequent sending of ships and planes to conduct close surveillance on China seriously harm China's national sovereignty and security," said foreign ministry spokeswoman Mao Ning&nbsp;while speaking&nbsp;about the incident.</p>

<p>He&nbsp;demanded&nbsp;Washington "immediately stop this form of dangerous provocation".</p>

<p>The United States military had earlier stated that a Chinese fighter pilot carried out an “unnecessarily aggressive manoeuvre” around an American surveillance aircraft flying over the South China Sea last week.</p>

<p>The incident, which the Pentagon called a common behaviour of China, occurred at a time when tensions had already escalated between Beijing and Washington after the latter shot down an alleged Chinese spy balloon which was spotted traversing the skies of the United States. The ties were further strained over the issue of Taiwan as China increased military aggression near the island.&nbsp;</p>

<p>The Chinese plane “flew directly in front of and within 400 feet of the nose of the RC-135, forcing the US aircraft to fly through its wake turbulence” on Friday, stated the Indo-Pacific Command (IndoPaCom) in a statement.</p>

<p>“The RC-135 was conducting safe and routine operations over the South China Sea in international airspace, in accordance with international law,” the command added.&nbsp;</p>

<p>A senior US defence official stated that there has been an “alarming increase in the number of risky aerial intercepts and confrontations at sea” by Chinese aircraft and ships – actions that “have the potential to create an unsafe incident or miscalculation”.</p>

<p>“We don’t believe it’s done by pilots operating independently. We believe it’s part of a wider pattern," the official stated.&nbsp;</p>
