SAN DIEGO (KGTV) - A San Diego company created technology for NASA's 2020 Mars rover, launching in July.The Perseverance is set to launch July 20, at 9:15 a.m. EST.NASA's been working on this project for more than a decade, drawing from past missions with hopes of finding evidence of past life on the red planet."It's a really exciting mission!" Mike Carpenter, VP of Engineering at KULR Technology said."We don't know for sure what they're going to find, but if they find any hard evidence of life that would be wonderful." Carpenter is thrilled to be a part of this mission, bringing a piece of San Diego to Mars.Carpenter said the company is known for it's technology that keeps batteries from exploding.For the rover, they created heat sinks that control the temperature around sensitive instruments. Specifically the heat sinks on Perseverance protect SHERLOC, a detector on the arm of the rover that looks for signs of past life.KULR sent similar tech to Mercury, but this is their first trip to Mars."It is the largest most sophisticated rover NASA has sent there," Carpenter said.According to NASA, Perseverance will be landing in the Jezero Crater, the site of an ancient river delta.The mission has four Science Goals:1. Determine whether life ever arose on Mars.2. Characterize the climate on Mars. (Seeking to find if an ancient climate could have supported life.)3. Characterize the geology of Mars.4. Prepare for human exploration."This science goal relates to national space policy for sending humans to Mars in the 2030s." 1547

SAN DIEGO (KGTV) -- A local father is recovering from stab wounds after getting attacked by an intruder in his home. The man's 20-year-old son shot and killed that intruder according to San Diego Police. It happened just before 6:30 Tuesday morning at a home in the 6300 block of Lake Shore Drive in San Carlos. Neighbors heard the violence. "I heard the gunshots, it was like three or four gunshots, then screams for help immediately after," said Denise Rolla. When police got to the home, they found the suspect dead in the pool and the 54-year-old homeowner with stab wounds to the upper body. Police say the homeowner's son shot and killed the intruder, who stumbled out the back and landed in the pool. "I heard what turned out to be the suspect fall into the pool and then a couple minutes later, you could see the blood start to spread out through the pool," said Andrew Grogg, who lives right next door. There are walking paths and Mission Trails Golf Course is located behind the homes which are just southwest of Jackson Drive. Neighbors say they don't have a problem with transients in the area, but police say so far, it appears the 38-year-old suspect is homeless. His name hasn't been released. The family owns a tire shop in La Mesa. They are well known and liked in the community. "They're local business owners in the community. They're great neighbors. They're kind, they're nice," said Grogg. Police say so far, the attack appears to be random. 1472

SAN DIEGO (KGTV) - A plan to improve bike access along Harbor Drive may put pedestrians at risk.As SANDAG works to promote alternative transportation through its "Keep San Diego Moving" initiative, they plan to upgrade the Bayshore Bikeway.That includes a stretch through Barrio Logan that runs along Harbor Drive from 32nd Street to Park Boulevard.Renderings from SANDAG show a two-way bike lane protected from traffic by concrete or plants.But, plans to build the bike lanes also call for the removal of two pedestrian bridges that go over the intersection of Harbor Drive and 32nd Street. SANDAG will replace the bridges with crosswalks.Navy personnel use the bridges as they go to and from Naval Base San Diego every day.Some people who use the bridge daily say they're worried that it will lead to more accidents and dangerous conditions while trying to cross. Others say it could lead to more people jaywalking along Harbor Drive.SANDAG told 10News that safety is their top concern, and the new crosswalks will "enhance the entire intersection, including adding pedestrian pushbuttons, striped crosswalks, median landings, and other safety features."SANDAG also says they're working with the Navy and other city organizations to make sure the crosswalks are as safe as the bridges. A spokesperson for the Navy was unable to provide a comment about the project.Right now, the project is in the environmental review phase. Construction is expected to begin in the summer of 2020 and wrap up by the end of 2021. 1523
